IMPROVEMENT m DEMIJOHNS.

Specification forming part of Letters Patent No. 174,104, dated February 29, i876; application filed November 10, 1875.

To all whom it may concern Be it known that I, GEORGE W. BANKER.

I of the city, county, and State of New York,

have invented a new and useful Improvement in Demijohns, of which the following is a specification, reference being bad to the accompanying drawings forming a part thereof.

Figure 1 is a vertical central section of a demijohn containing my improvement. Fig. 2 is a similar section of the bottle covered by an elastic packing or coating. Fig. 3 is a perspective view of the bottom of the exterior case of the demijohn, provided with apertures to admit light into the interior of the bottle, and Fig. 4 is a perspective view of the exterior of my completed demijohn.

My invention relates to a d emijohn in, which the bottle is protected by an elastic covering; and consists otaflfluid-holding bottle, made of glass or other. f angi le material, coated with an d e fi t-Stic substance, inclosed l a rigid" BXtQIiOI case,"preferably similar in form o t bottle, in which the bottle fits p lyt 9 that the inner surface of the extee is substantially thronghoutin contact i the covering of the bottle, thereby tendng to prevent-any movement within the case the bottlewith its adherent covering, and

Qonsequent abrasion or displacement of the I latter. ,A bottle thus inclosed is very'securely a protected against fracture, while the bottle and case together occupy but little more space than the bottle alone, and form a demijohn that is ,very' convenient to transport and handle.

In'carrying out my inventioml coat the bottle which constitutes the fluid-holding receptacle of my demijohn with a covering of apermanently-elastic material which will adhere thereto. The material which I find most convenient and economical is glue with which is mixed a small proportion of glycerine. After this coating is applied-over the surface of the bottle, to the thickness of from onesixteenth to one-eighth of aninch or more, depending uponthe size of the bottle, while the mixture is still plastic, 1 prefer to apply a covering of ground cork. .This is done by rolling the bottle, with the plastic material described adhering to it, in a quantity of the cork, so as to cause a considerable coating of it to became embedded in and adhere to the glue.

In the drawings, A indicates the bottle, B, the elastic adherent coating, and G the covering of ground cork. If preferred, the ground cork may be mixed with the glue before the latter is applied to the bottle, so that the cork will be thoroughly incorporated with the glue. If the demijohn is intended to hold warm fluids, I apply a covering of paper or cloth to the glue and cork. This is done while the glue is still warm or adhesive, so tha the paper or cloth will adhere to it an stitute a close permanent envelope envelope is represented in thed by the lines designated hyfthe lette is the exterior case, 'made preferabl Sheet'of wood bent into a cylindrical for and necked to conform to the shape of the bottle by' cutting out gores or-trianguler pieces and gathering in upon the bottle the remaining sections, as seen in Fig. 4:. Upon the case thus formed I place hoops. In the drawing are represented two, one, a, at the Fig. 3

bottom, and another, a, on the neck. represents the bottom of the case I), made to fit into the lower end of the said case. It is preferably provided Wllll apertures, 6, through which light may be admitted to the interior of the glass bottle. f f are two metal ribs extending from above the hoop e to the bottom of the case, the lower ends being hentinward over upon the bottom, to which they are nailed or otherwise secured. The hoops are put on over these ribs, and may be secured to them. A greater number of ribs may be applied, so that the bottom D shall require .no other to retain it in place in the case than the lower ends of these ribs turned inward and secured to it. The upper ends are per-' ering, containing my improvements. -do not intend to limit myself to the parfurnishes a protection to the bottle against external violence from transportation or handling.

I have thus described what I regard as the best method of fabricating a demijohn, with abottle protected by an adherent elastic cov- But I ticular material named for the elastic adherent covering for the bottle, nor to the precise manner described of applying it. The essential requisites are that the material for the said covering shall be permanently elastic and adhere to the bottle, and, with reference to the exterior case, that it shall substantially conform in shape to the bottle and fi-t it snugly. I would recommend that the entire surface of the bottle be covered by the adherent elastic coating. But, if preferred,

this coatin may be applied in separate bands surrounding the bottle, or otherwise, so as to adequately protect it.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. A demijohn,consisting of a bottle provided with an elastic adherent covering, inclosed in an exterior case similar in shape to the bottle, as and for the purpose described.

2. A demijohn-bottle provided with a permanently-elastic adherent covering, as and for the purpose described.

3. A demijohn-bottle provided with a permanently-elastic adherent coating and a paper or cloth envelope adherent to the elastic coating, as and for the purpose described.

Witness my hand this 6th day of November, 1875.
